You probably think about water pressure and temperature when you shower. With a new digital shower system out this fall, Kohler wants to give you a lot more to think about.

It's called DTV+. A touchscreen panel built by Elmhurst-based UICO inside the shower will allow users to select from a variety of water, light, steam, color and audio settings. These can be customized or selected from a catalog of pre-programmed "experiences" created by Kohler, which debuted DTV+ last week at the Kitchen and Bath Industry Show in Las Vegas. The new product upgrades the company's DTV system, launched in 2006, and introduces those pre-programmed sensations, which will help users relax and recharge, the company says.

"This will allow homeowners to experience truly spa-like experiences in the convenience and privacy of their own homes," the company says on its Web site.

Asked to provide details on the DTV+ "experiences," a Kohler spokeswoman said it was too early to comment.

The DTV+ control panel will be fully touch-controlled — no easy development task given the challenges of integrating touchscreen technology in wetness and humidity. UICO chief executive Bahar Wadia said the waterSense capability in his company's duraTouch screens allows computers to differentiate human touch from liquid contact. Due to their ability to withstand moisture, the screens are used in a variety of settings, including in McDonald's kitchens, on oil rigs and in medical facilities.

Drawing from those applications, UICO built a screen that could work in a shower. Wadia said it took a year and a half to get the DTV+ panel right.

Safety was a major consideration, since improper setup or construction could mean electrocution. Another concern was longevity.

"Unlike an iPhone, which you change out every two years," he said, "once you put in a bathroom fixture, you use it for three, five, even 15 years."

The Kohler spokeswoman said the DTV+ system's price has not been finalized but will likely cost thousands of dollars.

Wadia said he thinks this could be one of many touch screen-enabled features in the bathroom of the future.

"I believe UICO's products can extend all the way from showers to spa controls to faucets to toilets," he said. "Toilets in the states aren't as exotic as they are in the other parts of the world, especially Japan."

A recent Pew survey on smartphone use reported that 40 percent of young adults said they use social media in the bathroom. Perhaps in the future, they'll be able to tweet from the toilet, even without their smartphones.
